Title: Autopsy Room Hazards Here starts the lesson!
Contents Introduction - Overview of Autopsy Room Hazards - Importance of understanding risks in the autopsy room - Potential sources of infection for forensic pathologists and staff
Classification of Pathogens Hazard Group 1: Unlikely to cause human disease Hazard Group 2: Causes disease; hazard to employees but not community; treatable Examples: MRSA, VREF, Salmonella spp. Hazard Group 3: Causes severe disease; serious hazard; treatable Examples: Mycobacterium tuberculosis, HIV, HBV, HCV, CJD prion Hazard Group 4: Causes severe disease; serious hazard; likely to spread; untreatable Examples: Ebola, Lassa, Marburg, Covid-19.
‘High risk autopsy’ Is the postmortem examination of a deceased person who has had, or is likely to have had, a serious infectious disease that can be transmitted to those present at the autopsy, thereby causing them serious illness and/or premature death Significance of HG #3 and HG #4 Lack of medical records or inadequate information Risks from unknown infections and hospital-acquired infections
Definitions Risk: Chance of acquiring a blood-borne infection from sharp injuries (HBV, HIV) Hazard: Danger posed by instruments like knives, saws, or needles High-Risk Autopsy: Postmortem of a deceased with a serious infectious disease
Routes of Infection in the Autopsy Room Infection Routes: Wound contamination (e.g., scalpel, needle-stick injuries) Splashing infected blood on open wounds Contact with mucous membranes (eyes, nose, mouth) Inhalation and ingestion of aerosolized particles
Commonly Acquired Infections Hepatitis B (HBV) High transmission rate, preventable by vaccination Increased risk for forensic pathologists Hepatitis C (HCV) Significant risk from needle-stick injuries Tuberculosis (TB) High risk of transmission during autopsy Airborne droplets, more infectious postmortem
HIV Infection Risks Low but Present Risk Viable HIV found in various tissues up to 5 days after death Risk factors: deep injuries, needle-stick injuries with visible blood Suspected cases: Male homosexuals, IV drug users, etc.
Universal Work Precautions Access and Immunization Restriction of unauthorized person Immunization against tetanus, poliomyelitis, TB, hepatitis B Precautions for immunosuppressed or immunodeficient individuals Protective Clothing Full-sleeve overalls, head cap, N95 masks, goggles, double gloves, waterproof boots Plastic visor for eye protection
Handling Sharp Instruments Safety Measures Use of blunt scissors, minimal sharp instruments Avoidance of needles where possible Proper disposal of sharp items in puncture-resistant containers
Specimen Handling and Disposal Proper Labelling and Fixation 10% formalin solution for fixation Gloves for handling specimens Disposal Procedures Use of glutaraldehyde for instrument sterilization Incineration of soiled materials Special handling for laundry materials
Clean-up Procedures Blood and Body Fluid Spills Wipe with disposable tissues, clean with 1% bleach solution Disinfection Use of sodium hypochlorite, Betadine, ethanol, hydrogen peroxide, and other disinfectants
Accidental Injuries Immediate Response Washing and disinfecting wounds Reporting and testing for HIV and HBV Counseling and follow-up testing
Autopsy and Disposal of Radioactive Corpse Radiation Safety Protective clothing and long-handled instruments Proper disposal and handling of radioactive materials Special procedures for high-radioactivity cases
precautions Importance of precautions to prevent infection - Role of protective measures and proper handling in autopsy safety - Continuous education and awareness for autopsy personnel
